Adding value to paint technology

When every bucket of paint is green

Marine paints made with tin and copper could be replaced by a more environmentally-friendly alternative if a Victoria University project is commercialised.

The School of Chemical and Physical Science has found a new chemical, nano-structured calcium silicate (NCS), which can have silver attached to provide anti-microbial effects without causing environmental concerns.

NCS may also be used in architectural paints to add whiteness and opacity, and it is being tested to replace the flatting agent and titanium dioxide commonly found in interior paints.

The end result is paint with anti-microbial properties without the use of copper or tin.

Viclink is seeking partners to commercialise this work.
